The standards that I am addressing are related to RI GSE: LS2 (9-11) -3 Students demonstrate an understanding of equilibrium in an ecosystem by …
3a defining and giving an example of equilibrium in an ecosystem.
3b describing ways in which humans can modify ecosystems and describe and predict the potential impact (e.g. human population growth; technology; destruction of habitats; agriculture; pollution; and atmospheric changes).
3c describing ways in which natural events (e.g. floods and fires) can modify ecosystems and describe and predict the potential effects.
This unit focuses on parts 3a and 3b and doesn't really touch upon 3c.
For more information regarding this particular standard, please check out the RI Science Teachers Wiki for this specific GSE: LS2 (9-11) -3
The learning objectives for this unit are for the students to understand how ecosystems are in a balanced state of equilibrium. I also want students to investigate different ways that humans have had an impact on an ecosystem.
By the end of this unit students will be able to:
Define what it means to be an open system.
Visualize how the biotic organisms in an ecosystem depend on each other.
Explain what happens when a species or niche is removed or limited in an ecosystem.
Analyze the effects of biodiversity in an ecosystem
Define what is meant by invasive species
Synthesize a fact sheet of a particular invasive species and analyze how humans have played a role in the introduction of this particular species
Describe at least three human activities that impact the environment around them.
Predict how the habitat lost in the bay might have an impact on the organisms that are living there.
Explain what a watershed is and identify what watershed that they inhabit
Explain the difference between a point source and a non point source
Identify three sources of pollution in the bay or watershed
Conduct an investigation of how pollution travels through watersheds into the Bay
Explain what eutrophication is and predict how that might impact the ecological balance in the bay.
Define global warming
Summarize the effect of increasing carbon dioxide on temperature
Identify pattern and trends of increasing greenhouse gases in the atmosphere
Graph the trend of increasing greenhouse gases
Interpret the curve of a graph and make a prediction based on the data curve
Asses the effects of global warming on Narragansett Bay
Hypothesize how global warming might impact us in the future
